Top favorite/least favorite Kamen Rider series

[Itami]

Was bored so I figured I'd make this topic. List your favorite Kamen Rider series you've seen, or your least favorite, or both. I'll keep mine simple as a top 5 best and worst. Can turn into civil discussion, though primary focus is making a list.

Edit June 1st, 2019: Changed #5 best to Zi-O on further watching and reflection.

Top 5 best rider series:
1. Ex-Aid
2. Gaim
3. Kabuto
4. Den-O
5. Zi-O

Top 5 worst rider series:
1. Drive
2. Ghost
3. Fourze
4. Hibiki
5. W

Hmm, let's see here...

Top 5:
1. Gaim
2. Kabuto/Den-O/Double
3. Ex-Aid (Which surprises me because when it was first announced I didn't like the designs, but they grew on me. lol)

Bottom 3: (In no particular order.)
1. Ghost
2. Drive
3. Wizard

I've watched some of the other Heisei series, but they fall somewhere in the middle so they didn't make the cut. I also didn't include series I haven't had a chance to watch yet like Hibiki or Kuuga. For the bottom 3, they all had elements I liked, but overall I just didn't like them in the end.

3. Ex-Aid (Which surprises me because when it was first announced I didn't like the designs, but they grew on me. lol)

The suit designs are still very bad to me by a big margin outside of two. The belts aren't that great either and that final form is really bad. Yet the series itself was so good I overlook the designs and enjoyed a lot more out of it. Some shows can have amazing design (Wizard) yet fall flat too.

I think that might be me to an extent. The suit designs took me awhile to get used to aside from KR Para-DX and like you, I think it had a bit more due the story than anything else. I didn't get the final form either. I'd take Beast's final form if they were to do that frilly stuff any day.
